Filed: 1981-02-18
Abstract: PURPOSE:To automatically supply the required amount of gas with required pressure, by providing a high pressure switch and a low pressure switch in a gas pressure supply pipe and operating a volume controller or a gas compressor by said pressure switches. CONSTITUTION:When requiring high gas pressure supply, a low pressure switch 6 is thrown in to excite an electromagnetic valve 3A to perform the gas pressure supply with 1/4 capacity of a compressor 1 through a volume controller 2A. When the compressor 1 is operating at 1/4 capacity and the contact 8A for the low pressure switch is closed, an electromagnetic valve 3B is excited to operate the compressor 1 with 2/4 capacity through a volume controller 2B. Similarly the compressor 1 performs the full capacity gas pressure supply through electromagntic valves 3C, 3D. While when the gas pressure supply is low, a high pressure switch 5 is thrown in to reduce the capacity of the compressor 1 in the opposite manner to reach to zero capacity finally.

Filed: 1990-01-31
Abstract: PURPOSE:To hold concentration of a perfume in a room at a specified value regardless of a fluctuation in a feed airflow of air conditioning air by a method wherein a feed amount of a perfume is controlled by means of the detecting value of at least one of a pressure in a feed duct and an air temperature in a room. CONSTITUTION:An airflow of air delivered with the aid of an air pump 40 is regulated by a mass flow controller 42 and guided to vegetable refined oil in a container 44 for bubbling. By the bubbling, phytoncide is dispersed and guided to an air conditioner through a feed pipe 45, and is fed in a room 10 togetherwith air conditioning air. A current responding to the detecting value of a pressure sensor 29 located in a feed duct 14 is outputted to a feed fan 18, and rotation thereof is controlled approximately proportionally in response to a current. Since when an airflow of feed air is increased, an air pressure in the room 10 is increased, by increasing an air bubbling amount, an amount of phytoncide fed in the room 10 is increased. When an airflow of feed air is low, an air bubbling amount is suppressed, and an amount of phytoncide fed to the room 10 is decreased.
